PHYSICS Brake ducts and Tyre damage

In the change log it says that tyres degradation and track abrasivity have been changed: now we have more or less degradation?

 

@Aristotelis what about the correct temperature range fro brakes, 500-900 is it correct?

 

@Aristotelis Hi! Yesterday we have small fan race on Lambo ST, and nearly half or drivers has some tyre problems after 5-6 laps. It was so slippery, like in rain. If i'm not mistaken, now everybody has 1.0.7, and tyres are the same for all. How to understand, what was that, if it depends on driver style, and how to control this phenomenon?

 

No the track was optimum, the half of drivers were fine, and the other were struggling for grip and lost over 2 seconds per lap. Is it graining or something else?

Ok, sorry for offtop. Would you be so kind and give me a link on this info?

 

If brake temperature is disabled, the brake ducts setting has no effect?

 

@Aristotelis . I have a question about tires conditions and how to get maximum from them. Now there is Mclaren Shadow event. I found that after 3 laps, my pace is getting worse and worse and the worst lap is usually 5 or 6. I did a lot of runs and always see this trend. Here is my best attempt so far () and you can see my driving style. What am I doing wrong? I found the more I attack, the worse times I have after 3 laps. I see how I loose time on straigths even when I have the same exit from the corner. What is the reason from developers point of view? I suppose the reason is the tires, because fuel is getting lower. How should I drive to have tires in better conditions? Are there any tips? Just would like to see your point of view. Yeah, setup is default aggressive without any changes.

 

Nice driving, your rear left tyre is getting up at 100c, maybe this is causing the drop in performance. My rear left is the same.

 

Yeah, I also think about this. Cannot understand how to improve else want to see the laps of the guys, who run 11-47 on finish. Just interesting. If I do perfect laps I can have 11-50, or 11-49 high, but 11-47 is just unbelievable

 

One question? where can I see the temperature of the brakes ? Tnx

 

Guys, I'm not sure if this thread is exactly the right thread to ask this question in so please delete if so...

Quite often I'll see that my tyres are overheating across the whole contact patch, changing colour to a yellowish tint. While this is happening, the pressures still remain in a good range (27.5-28)

I'm a little lost with what I should be doing to stop this happening. Should I be lowering the pressures to give me more room for temperature increases or would the same thing still happen due to what is most probably poor driving technique?

 

Some yellow is fine. I would not lower your PSI as they are in the window.

What exactly is your tyre temps?
What setup are you using?
What car are you using?
What is the track temp?
What is the track?

 

@EsxPaul

 

Thanks for the info

From memory, the tyre temps when yellow were
105c and 28psi
Aggressive setup
Nissan GTR but I seem to do this with all cars
30c track temperature
Silverstone

It's common for this yellowing colour to occur within 4 to 5 laps, at which point I find the car more difficult to keep on the track even though the tyre pressures are remaining quite constant.

My hunch is that it's my poor driving style causing a vicious circle. Tyres go yellow, car gets looser and I start to miss the apexes because I don't want to back off. The laptimes start getting worse and I eventually end up off the track

 

@EsxPaul - 105 is ok. Silverstone has some high energy corners.

Is it the left hand side tyres only?
what lap times are you doing?
Do you receive this on safe setup?

 

It's most often both of the rear tyres. I'm one of the more slow drivers out there and my average lap time would be in the 2:03s.

I've always used the aggressive setup against the AI and never paid attention to lap times or tyre temps until I realised how much slower than average I am. Since then I've been trying to push the car harder and getting frustrated as I can't find any improvement.

I've had some excellent help and advice from @n1lyn recently, where he kindly analysed and compared one of my laps against his. My problem is that I don't have the skill to put his tips into practice regarding my inputs.

If I'm honest, I'm driving whilst being angry with myself and trying to force the laptimes down in a different way to that which was advised.

Reading my post back, it might be time for me to calm down and take a break from it

 

Ideas without seeing your driving (thanks for the kudos btw, but as long as you're not faster, we're not done here):
- reduce camber by 1 or 2 clicks,
- increase rear brake duct by 1
- move brake bias forward a little
- use higher tc to get less slip

is the car very oversteery? -> change Aero-Balance a little (~0.5%) more backward by lowering the rear ride height or more wing. only really do one or 2 clicks at a time. Aero changes are often quite severe.

or try playing with rear rollbar.

That's enough for a day of practice

Remember: when u change anything that lowers rear tyre temperature, that will also decrease tyre pressure, so you will need to add something back after your changes.

 

Thanks for all the extra tips. That gives me some homework to be getting on with and I will give all of the above a try
